The "Error 500" appears if i
1. Create a new post
2. I create a new category

If I am able to remove the new category then the index.php could be accessed and everything work fine. If I create another new category an "Error 500" appears again.

Hm, this seems to be related to a faulty webserver setup.

Can you try and download XAMPP instead; s9y works properly with that system.

Apache2 with PHP5 is known to cause trouble in threaded mode, and you seem to be using a special CGI method which can on top of that create more trouble.
